How to import a 3d object by csv file
With a text file like this:

test1;E:\yourpath\file1.blend\Object\;Cube
test2;E:\yourpath\file2.blend\Object\;Sphere


Where:


First field: a name
Second field: the complete path to your object
Third field: your object name


You can:

import bpy
import csv

textFile = 'E:\\Blender\\yourpath\\import.txt'

with open( textFile, 'r' ) as file:
    reader = csv.reader( file, delimiter = ';' )
    for row in reader:
        bpy.ops.wm.append( directory=row[1], filename=row[2] )
